08B-2 hardened hub sprockets

08B-2 hardened hub sprockets have two tooth rims for duplex 08B-2 chain of 1/2" (12.7 mm) pitch to DIN 8187 / ISO 606. The teeth on both rims are induction-hardened, which increases their abrasion resistance.

08B-2 hardened sprocket for heavily loaded machines in tough conditions

A duplex drive transmits more power, and a hardened sprocket keeps its tooth profile longer - a combination for heavily loaded machines working in tough conditions. The C45 steel hub remains soft, so you can machine the bore for your shaft.

08B-2 duplex sprockets with induction-hardened teeth

08B-2 duplex sprockets in C45 steel with teeth hardened to 45-55 HRC. 08B duplex sprockets with unhardened teeth can be found in the Hub sprockets group.

Frequently asked questions about 08B-2 hardened sprockets

Can a hardened sprocket be welded?

Welding near the teeth is not recommended, as the high temperature can destroy the hardening effect. Use a key and a set screw to connect it to the shaft.
